Switched capacitor voltage converter. Industry standard 7660 charge pump in so 8 package. Diode steered charge pump type of voltage doubler.
The circuit action is very simple as follows.
The simplest of these circuits are a form of rectifier which take an ac voltage as input and outputs a doubled dc voltage. Each voltage doubler takes a dc input and outputs a doubled dc. In general an n stage dickson or doubler charge pump can be modeled as an ideal voltage source with an open circuit output voltage approximately equal to n 1 v ddand an ideal series output resistance r out id n fc where c is equal to c dkand 2c. The pump consists of d1 c1 d2 c2 and is driven by the low impedance squarewave output of pin 2 of the ic.
